5 Claims. (Cl. ZBO-39) This invention relates to a bushing structure and has special reference to a bushing structure as employed particularly in the construction of metallic barrels and other containers, such, for example, as may be used in storing or in shipping oils or other liquids or semi-liquids, a bung or stopper being associated with the bushing struc-f ture in order to make the latter fluid-tight.

More particularly, this invention relatesto a bushing. structure comprising an internally threaded body portion secured within a socket formed by a flange which latter is preferably struck outwardly from the barrel or other container. It is also preferable that the flange mem-` ber be formed integrally with the barrel Wall or other supporting body with which it is associated.

Heretofore, in bushing structures provided on Y barrels and other containers, it has been impossible to drain the entire contents thereof for the reason that the bushing assembly usually project-y ed a substantial distance within the interior of the barrel. In the present construction, it will be apparent that by means of forming the ange in a plane outside of the inner wall of the barrel, the contents of the barrel will have no obstruction to its outward flow.

In order that .the internally threaded body'v portion be securely positioned against turning within the socket formed by the ange and in which the body portion is disposed, the outer edges of the latter are recessed or provided with notches into which the walls of the flange are formed. Further, in order to guard against the unauthorf ized opening of the barrel or container, a new and novel means is provided for sealing the bung or stopper engaging the `bushing structure.

Other objects Aand advantages will hereinafter be referred to and for a better understanding of the nature, scope and characteristics of this invention, reference may be had to the accompanying drawings and the following description, in

which drawings:

. bushing structure;

Fig. 5 is a perspective view of a preferred form of sealing means; f Fig. S is an end view of a portion'of a barrel head showing the body portion and sealing member loosely engaging the flange portion Yof the '5 Fig. `'7 is a vertical sectional view taken'on theA line 1,-1 of Fig. 6; n

Fig. 8. is a vertical sectional view similar to Fig. 7 showingV the body portion and sealing member l0 in an assembled relation, together with a bung in threaded engagement with the body portion; and Fig. 9 is a fragmentary sectional view taken on the line 9 9 of Fig. 8.

Referring now to the drawings and more parl5 ticularly to Figs. l to 5, inclusive, the barrel head I0 or supporting wall of any container is' shown and is preferably formed of a sheet material such as steel. A flange portion II is preferably integrally formed with the barrel head I5 and pro'- 20 jects outwardly therefrom to form a socket. This ilange portion is formed from the material surrounding an annular opening in the barrel head.

The socket I I is preferably polygonal in its pe-` ripheral contour to receive a main body portion 25 I2 of a similar peripheral contour whereby the main body portion isl prevented from turning in the socket. Thematerial'of the main body portion is preferably a casting ofa malleable iron or other suitable material. 30 The main body portion may be formed of any1V number of edges and although it is preferably polygonal and regular in its'peripheral contour, it is to be understood that this is merely for convenience in the assembly of the'bushing'str'ucture and that any vnon-circular''peripheral contour may be employed. `'I'he edges of the body portion are provided with a plurality of notches I3 or recesses in order to more securely grip the retaining wall o'f ithe socket II which,Y as will 40 hereinafter kbe more fully described, is formed thereagainst. However, it is to be understood that each of the laterally extending edges' may be of the socket II, in addition to engaging the tapered edges of the body portion, are formed into the recesses or notches I3 thereby affording a more secure relation therebetween than could be obtained by merely the engagement of the polygonally shaped contours thereof.

f As shown in the drawings, the depth of the notches is uniform throughout their lengths The notches are also of uniform width. However, this is merely for purposes of illustration and it will p be apparent to one skilled in the art thatthe barrel whereby thefull contentsthereof may be 5 A bung I 4 comprising a bore portion I5 and a flange portion I6 engages the internally threaded body portion I2. A sealing gasket IIis interposed between the flange I6 and the socket, the gasket, of course, serving to prevent leakage of the-fluid content in .the barrel. A projection I8 is formed on the outer periphery of the flange IG Vand preferably integrally therewith, the projection havingan aperture I9 therein. In instances where the barrel or other container is used for local storing purposes, it mayv not be necessary to employ a sealing element. However, in theshipment ofY oil or in other instances where the container has left the owners hands, Ait is desirable tofguardagainst the unauthorized opening ofthe barrel by means of a sealing member.- In the construction which will now be described, the manufacturer of the barrelmay. or may not include the sealing means in the bushing structure just prior to the shipment of the barrel; whereas, in the usual Vconstruction, the sealing means -is included in the bushing assembly and is necessarily,` made yup when the barrel is `in the process of manufacture. A wire 20 is placed around the inner portion kof the socket adjacent thebarrel head IB and the ends thereof are twisted together tightly in order to permit the wire to conform fto theperipheral contour ofthe socket. The twisted. ends `2I Vof the wire 2II `are inserted in the apertureV I9 in the projection I8 ofthe bungjwhereafter a sealing means ofthe usual type is disposed thereon.V

Heretofore, it has been usual that the manufacturer have on hand a number of containers without sealing means and a further number with sealing means. The `present construction provides that the manufacturer may make up all of the containers without sealing means whereafter sealing means are provided as they are wanted. This sealing member, as formed by the peripheral contour ofthe socket, is shown more particularlyfin Fig. 5 of the drawings,

Referring now to Figs. 6 to 9, inclusive, a sealing member of a. furtherform is shown.l A barrel head 23 is shown having ,a polygonally shaped socket portion 2l formed outwardly from the materialsurroundinga hole 25 in a supporting portion of the barrel head, an internally threadedv body portion 26 being disposed in the socket 2l. The body portionV is preferably polygonally shaped to conform to the polygonally shaped socket 24 and the edges of the body portion converge inwardly from the larger diameter thereof. The inwardly converging edges have a plurality of substantially vertically extending grooves formed thereon preferably of the same depth throughout the length thereof; The side walls of the socket are `'formed against the inwardly converging edges, the material thereof engaging the grooves.

A collar member 2'I of a size and shape to conl0 forrnwith the outer portion of the socket 24 has tion 3| and a flange portion 32, is in engagement with the internally threaded body portion 26, a 15 gasket 33 being interposedk between the flange member and the socket in order to prevent leakage therebetween. It may also be desirable to interpose a gasket 33a between the flange of the socket and the main body portion 26 in order to 20 prevent leakage through the bushing structure. A projection 34 is formed on the flange member 32 and has an aperture 35 for receiving a sealing wire36 which extends through an aperture of one of the ears 28. The ends of the sealing wire 25 36 are sealed-together in the usual manner.

By referring to Fig.-9 of the drawings, it will be noted that the Amaterial of the collar member 21 and the wall of the' socket 2| are formed into thek notches provided in the body portion 26. In 30 order to secure the collar member 21 in such a relation with the bushing structure, the collar portionv is formed at the same time that the wall of the socket'is formed against the inwardly converging edges of the'body portion. The manner 35 of forming this structure will now be briefly described. Fory amore completer description thereofyreference may be had to a copending application lfiled of even date herewith and bearing Serial No. 217,031. 40

A barrel'head blank, provided with an aperture in any Well known manner, is interposed between a punch and die member whereby the material adjacent the aperture isformed into a socket, the walls of the latter being yformed pref- 45 erably at substantiallyright angles to the barrel head. An internally threaded body portiony is disposed in the socket, whereafter the barrel head is placed on a die member, preferably comprising aseries of segments pivotally mounted on a. sup- 50 porting structure, one segment being required for each inwardly converging edge of the body portion. The segments are provided with pointed end portions for engaging the side wall of thek socket to form the material. against the inwardly 55 converging wall of the body portion.A However, in the present construction, a series of ridges mayl be formed on the engaging edge of the segment to'correspond with and be received in the grooves formed in thebody portion. If aflange collar be Vprovided on the outer side of the socket to be used as a sealing means, the collar is also formed into vthe grooves of the body portion, together with the side .walls ofthe socket.

While several embodiments of this invention are herein shown and described, it is to be understood that various modifications will be apparent to those skilled in the art without departing from the spirit andv scope of this invention, and therefore, the same is to be limited only by the scope of the prior art and the appended claims.
